"It also secures the park's public road access and gives us more options for developing visitor facilities in the future."
Nga Potiki representative Matire Duncan wrote to the regional council to advocate for the land purchase.
She said that the Papamoa Hills ridge line was an ancestral landmark and an outstanding cultural landscape that had been occupied by many different iwi over the centuries, including Waitaha, Ngati Ranginui, Ngai te Rangihouhiri, Ngati Pukenga, Nga Potiki and Ngati He.
"It's one of the most outstanding examples of pa and settlement complexes in the Pacific. Expanding the park to include those pa sites protects a storehouse of information about the early inhabitants of Te Moana a Toi (Bay of Plenty)."
Regional council's land management officer Courtney Bell said the current logging operation was progressing well.
"We're still expecting to be able to reopen the park later this summer."
